What rpm stall converter should use?

Very nice! I bet you miss it.

My first car was 1972 Duster. Bought it at the original Manheim Auto Auction in Manheim, PA. 318 column shift, slots all around with L60's on back. Had a lot of fun in that car!
You know I do. I had L 60’s on that car too, I bought it from an old lady when I was working at Felix Chevrolet, she was going to trade it in. It was like brand new she hardly drove it.
